A method is proposed to evaluate the required bracing stiffness for a one-story, multi-span 3D frame with non-uniform column axial force distribution and column bending stiffness distribution to achieve the specified buckling load without torsion. Stability analyses were conducted using the finite element method for a 3D frame with braces satisfying the required bracing stiffness obtained by the proposed method. As a result, it was confirmed that the specified buckling load corresponded well with the buckling load obtained by the finite element method, and the validity of the proposed method was shown.
